`IMPRVEMENT IN JOURNAL-BOXES.

The Schedule referred to in these Letters Patent and makingk part of the same.

I, EDWARD H. S'IEARNS, of Erie, in the county of Eric and State of Pennsylvania, have invented certain Improvements in Journal-Boxes for Saw-Mills and other machines, of which thc'following is a specification,

Nature and Objects of the I Mention. The first part of my invention relates to the use ol a detachable Babbitt-metal lining for journal-boxes,

extending the entire length of -thc box, and closely iitted and imbedded therein, so that`the water which is used to receive and convey away heat from it as fast Y as it may be developed byfriction with the journal, may be entirely excluded from contact with the journal itself, b1 t at the same time such lining shall be easily removable, so that when worn out it may be replaced by a new one; and in this cheap and simple manner the box itself will be protected against the effects of the heat developed by friction, while the journal itself shall have its heat borne away as fast as developed.

The second part of my invention relates to theA construction of the journal-box itself, with a large waternal, so that the water conveys away the heat of the lining, without at all coming in contact with the journal. 'lhe third part of my invention relates to the construction and location of an oil-chamber on'the outside of the box, but as a part of the same, in suoli a manner that-a reservoir of oil shall be kept in a position that is higher, considerably, than the longitudinal center ofthe journal, and shall be forced in contact with it, by its own weight, through wide recesses provided for it in the upper edge of the Babbitt-metal lining and under the cap of the box, so that this device forlubricating the jonrnal shall be self-acting.

The fourth part of my invention relates to thc immuting of the journal-box upon the frame in such a manner that, by the use of a wrist, a slot in thc frame, and a screw-shaft, the'direction ofthe journal may be changed whether in motion or at rest, by thc turning of a shn'ple crank, and by means of a screw-shaft they may be easily moved laterally at any tinn In thc accompanying drawing- Figure 1 represents -an end elevation ofmy improved journal-box;

Figure 2, a vertical crosssseetional view ot' the sa me Figure 3, a plan view of the same, thc cap and lining being removed; and y Figure 4, alike view of the Babbitt lining detached.`

v A is the cap.

hl E, the screw-bolts, by which it is secured to the box D. l

The oil-chamber a is a small chamber in the top of the cap to contain tallow, which will melt and run down npon thejonrnal, (when it becomes hea-ted,) through the holes m my, iig. 2.

15 is the Babbitt lining; and

C, its bed in the box; and

K K K K are the holes in the bed for the admission of cold water; and A q is the oblong opening therein, for the corresponding projection on the bottom of the lining to enter, and by which it is held exactly in its proper position, without either side or end motion.

Pis the wrist, before mentioned; and l,

G is the nut which is screwed upon the end thereof, so as to hold the box more or less tightly down against the frame, the wrist being rigidly xed in the box.

. S Sis the neck of the nut Gr, and over this neck the end of the screw-shaft F turns, when the direction of the journal and box is changed, as hereinbefole inti mated.

.'Ihe blank space on each side ofthe wrist at I, tig. 2, indicates the form of the slot in the bed-piece I, which allows of the lateral motion of the box andjournal, before mentioned, and this motion is impartediby means 'of the nut Hnpon the outer end of the'screw-shaft F.

The bed-piece I and the nut H are boxed together, as shown in tig. 1.

Fig. 4 shows, in a dctatched View, the simple form of i the Babbitt-metal lining.

,Ihe points O O O are those u-pon which the cap is received, while n n are the channels through which the oil is pressed bythe weight of the supply ot'it in the oilchamber D, and they should be tightly packed with cotton o1' cotton-wicking, which will regulate the flow of oil against the journal, which will cease altogether, ot

course, when the journal is at rest.

lheow of oil may be further regulatcdby its height in the chamber D.

'lhesc oil-chambers may be cleaned by simply removing the cap, without disturbing the journal.

The surface of the cap and box where they join together should be plancd smooth, so as to make tight joints, to exclude dust and prevent the escape of oil.

The unter-chamber in the box should be perforated with holes, as many in number and as large in diameter' as may be without too much impairing its strength as t support for the journal, in order that as much of the under surface as possible may be thrown into contact with cold water to keep it cool, and consequently thc journal also cool. l

In the side of the journal-box are holes d d, one fora pipe for receiving cold water, thc other for discharging the water after it hasbccome warm.

Incase a journal is driven by a belt horizontally, or

rom above, either with or without water-chambers, abbit-t linings may be provided and used iu the cap, .nd where a water-chamber is used in the cap it should omrnunicatewith the lower chamber so that the water nay pass through both. y

For many saw-mills and other machines the lcap may )e cast in one'piece of metal, planed, bored, and turned t perfect t, and east hollow with a chamber for t-allow, ;o be used as before explained.

It is believed to be manifest, from the foregoing de-v scription, that by the use of luy-improvements the fol- ,owing important results are effected First, thejournalis kept cool.

Second, an accurate and closely-fitting bearin g for the journal may be constantly had, by means of a detachable lining, removable and exchangeable at pleasure, thus securingvtrue action ot` the machinery.

Third, the lubricating-oil is furnished to the journal eiectually and automatically without Contact with water.

Fourth, an easily adj ustnble bearing is'furnishcd i'or the whole device.

Claim s.

a journal-box, in a` saw-null, having the projection described on its under side to t into a corresponding slot in the box itself, for the purpose of preventing both lateral and eudwise motion, substantially as and for the purpose set forth.

2. The water-chamber \V with its bed C, formed as described, having the oblong slot q for the reception of the said projection on the Babbittfnietallining, and pcrforated with holes KKK, and the cap A with its screwbolts aud'serew-holes, by means of which the box is closed and made fast over the journal, substantially as and f'or the purpose described.

3. The oil-chamber D, situa-ted with reference with the journal, as described, so that the weight of the oil thcr'ciu will force the same through the oblong openings n n, described, against the journal, ou a level wtll its longitudinal center, substantially as an d for the purpose described.

4. rlhe shaft F, bed-piece I and G, and nut H,in coinbinatiou, as au adjustable bearing for a journal-box, constructed and arranged substantially as described.
